Definitions

  • the invention relates to a mobile crusher unit having a supporting framework which is comprised of at least one crusher unit, a feed conveyor, and a discharge conveyor unit mounted thereto, and which can be relocated by means of a crawler undercarriage.
  • Mobile crusher units of the type described hereinabove are needed to reduce loose material such as ore, rock, coal or oil slate to a desired grain size.
  • the German DE 36 08 789 C2 describes a mobile crusher unit having a supporting framework that receives at least one crusher, and that can be lifted and relocated, in accordance with the advance of the removal of material, by a transport mechanism, preferably a walking-leg system or an extendable crawler or wheel undercarriage, and having at least one charging device which is associated with one crusher, and having a receiving hopper for the loose material delivered by freely transporting loading machines such as wheel loaders or excavators, and having a conveyor which feeds the loose material to a transfer hopper of the crusher.
  • the feeding device is required to be mounted in an arrangement swivable around a vertical axis at the supporting framework even during working mode.
  • a discharge conveyor unit which is composed of a discharge conveyor situated beneath the crusher and a dumping conveyor co-acting with the discharge conveyor, with it being possible for the latter unit to be of a mobile configuration with regard to the supporting framework.
  • An embodiment of this kind has a drawback in that it has a relatively large mass owing to the use of the additional discharge conveyor.
  • This additional discharge conveyor requires a drive and maintenance.
  • implementing this discharge conveyor adds on the weight of the mobile crusher unit, which is to be considered in the layout of the undercarriage motor power.
  • WO 2004/087324 proposes to install downstream of the crusher unit only one dumping conveyor unit which is used both for the discharge and for the dumping procedure, and which in terms of the supporting framework is designed and built as a component group that is swingable in horizontal and vertical direction.
  • Both the feed conveyor unit and the dumping conveyor unit can be configured as a plate-type belt, chain conveyor or belt conveyor.
  • the swing movements of the dumping conveyor unit should be triggered by means of any optional drive, more particularly by means of hydraulic or electro-mechanical drives.
  • crusher units or similar ones are comprised of a traveling gear which carries a bogie on which the supporting framework is mounted in a pivotable arrangement.
  • a disadvantage of such a structure is its relatively great construction height which necessitates a correspondingly long feed conveyor whose lower position is determined by the fact that the material to be crushed is discharged from wheel loaders, excavators or dumping trucks, for example.
  • Another drawback lies in the high mass resulting hereof.
  • AT 388 968 B is known a portable crusher unit for transporting the material over feeding hoppers, sieves, first conveyors and crushing devises to the last conveyor. All these elements are mounted on a common frame, which contains means of crawler undercarriage.
  • the present invention has the object of further developing a mobile crusher unit of the kind mentioned hereinabove so as to create the lightest possible construction form while ensuring high stiffness.
  • the mobile crusher unit according to the present invention which comprises supporting framework and traveling gear configured as a unit, with parts of the traveling gear serving as parts of the supporting framework, and with the crawlers of the traveling gear protruding into recesses and/or clearances of the supporting framework.
  • This measure particularly leads to a smaller height of construction which results from the fact that the traveling gear girder is merged with the supporting framework for the crusher unit, feed conveyor and dumping conveyor to one unit.
  • the gyratory arrangement provided according to prior art technology between the traveling gear and the supporting framework is deleted.
  • the low construction height also leads to the possibility that the feed conveyor whose maximum inclination is functionally limited can be built shorter so that the overall length of the mobile crusher unit is also reduced.
  • substantial weight is also saved which allows for a less costly fabrication of mobile crusher units.
  • the lower weight of the crusher unit also facilitates the shunting capability so that an omission of a gyratory and/or swiveling unit is not significant. Likewise, only one drive is needed for the crawler undercarriage which is completely integrated in the supporting framework structure.
  • the supporting framework can be configured as a solid full profile or in a trusswork structure, with the latter leading to further substantial savings on weight whilst assuring sufficient stiffness.
  • the supporting framework is preferably comprised of a U-shaped part with horizontally lying legs on the side averted from the feed conveyor, in which the crusher unit is arranged at the upper leg whilst the dumping conveyor unit is situated at the lower leg.
  • the supporting framework for supporting the feed conveyor which follows next to the upright standing basis of the U-shaped part is basically configured in form of a triangle. In other words, the whole supporting structure forms a uniform body which is geometrically composed of a triangular and a U-shaped part.
  • the dumping conveyor unit is preferably supported on the lower leg of the U-shaped part in such a manner that it can be swiveled around a vertical axis, i.e.
  • the dumping conveyor unit is so configured that it takes-up the material falling out from the crusher unit at a point which simultaneously lies on the vertical gyratory axis for the horizontal swiveling of the dumping conveyor.
  • the dumping conveyor unit takes-up the material falling out from the crusher unit at a point which simultaneously lies on the vertical gyratory axis for the horizontal swiveling of the dumping conveyor.
  • even further dumping conditions can be taken account of, for example floor irregularities in the area of a mobile crusher unit and dumping point of the dumping conveyor as well as dumping on other belt conveyors.
  • the integration of the traveling gear can preferably be so configured that the lower leg of the U-shaped part of the supporting framework is part of the traveling gear for the crawler arranged in this area.
  • a feed tank is situated in the bottom area of the feed conveyor which is preferably fastened to the supporting framework.
  • the mobile crusher unit has special advantages if the direction of travel determined via the crawler arrangement lies transversely to the longitudinal axis of the crusher unit.
  • the circumstance is taken account of in that an excavator excavates rock, ore or coal basically along an excavation route directed in parallel to the direction of travel of the crusher unit, so that the loose material is continually obtained along a line parallel to the direction of travel, along which the crawler undercarriage can travel without shunting operations.
  • FIG. 1 is a lateral view of an inventive mobile crusher unit according to the invention.
  • FIG. 2 is a schematic view of the supporting framework with the crawler undercarriage according to the invention.
  • the crusher unit shown in FIG. 1 is basically comprised of a feed tank 10 , a feed conveyor 11 in form of a feeder belt which rests on the supporting framework 12 , and furthermore it is comprised of a crusher unit 13 configured as a double-roller-type crusher and a dumping conveyor unit 14 which is shown here in an up-swung position as well as with a horizontal position designated with 14 ′.
  • the mobile crusher unit travels above the floor 15 by means of crawlers 16 , the traveling gear girders 19 of which are integrated in the supporting framework 12 .
  • the supporting framework 12 furthermore is comprised of a built-on structure 17 on which a driver's cab 18 is situated. The mobile crusher unit can be moved vertically to the drawing plane.
  • the supporting framework 12 with the crawlers 16 , the traveling gear girders 19 of which are integrated as part of the traveling gear in the supporting framework 12 is illustrated in detail in FIG. 2 .
  • the supporting body unit recognizable there is comprised of a U-shaped part with legs 121 and 122 as well as an upright-standing base 123 as well as a triangular part 124 and another body designated with reference number 125 .
  • FIG. 2 shows additionally, that the crawler 16 , which is positioned on the lower leg 122 of the U-shaped supporting framework extends into the room between the horizontal lying Legs 121 and 122 .
  • parts 121 to 125 form a structural unit which in this case shown here is represented by geometrical bodies that are separated here only for the sake of clarity.
  • Part 124 in particular, can also be configured in a trusswork construction style.
  • the dumping conveyor unit 14 rests on the lower leg 122 of the afore-mentioned U-shaped part, with the supporting point lying next to the constructively integrated crawler undercarriage.
  • the double-roller-type crusher is fastened to the upper leg 121 and arranged above the dumping conveyor unit 14 which can be swiveled by ⁇ 120° both in vertical direction, as indicated in FIG. 1 , and in horizontal direction, i.e. relative to a vertical gyratory axis lying in the drawing plane. It is technically achieved via a gyratory bracket.
